Reduce hum, expand your board, power all your pedals!
4,8 / 5,0 | 
As pedalboards grow, so does the need for sufficient power. Whether you’re in the market for your first board, or you’re (as many of us) expanding, or you’re setting up a secondary board for practicing or smaller gigs, you’re going to want to know about the best pedalboard power supply. Let’s take a look.

The Best Pedalboard Power Supply: What to Look For
It might not be the most romantic, most game-changing guitar-related thing ever. However, a well-built pedalboard power supply can make a significant difference on an ever-growing pedalboard with pedals that have ever-growing demands in amperes and volts. Therefore, consider these things first before selecting one.
When selecting a power supply for your pedalboard, choosing one with isolated outputs is crucial. These prevent ground loop hum and interference between pedals. Each isolated output acts like a separate power supply. Cheaper daisy-chain solutions may work in simple setups, but once your board grows or includes sensitive pedals, isolation becomes crucial.
Multiple Voltage and Current Options
Another key consideration is voltage and current compatibility. Most pedals run on 9V DC, but some require 12V, 15V, or even 18V. A more professional power supply will offer a mix of voltages and higher current outputs. Ensure that you check the respective requirements of your pedals to ensure the supply can deliver sufficient power to each.
Another factor to consider when selecting the best pedalboard power supply is its form factor and mounting flexibility. A power supply should fit neatly under or on top of your pedalboard without obstructing cabling or pedal placement. And lastly, consider the number of pedals you (will) need power for. This concerns both the current board and possible expansion.
As always, this list is strictly sorted by price, not any other metric.
